Re: [PHP3] PHP script to add users to .htpasswd From: Vamsi Nath (php <email protected>)
Date: 03/18/99

Thanks for the suggestion! Ok, I modified my function and now it looks like:

function valid_name($user) {

$file = file(".htpasswd");
$count = count($file);

$retval = true;

$i=0;
while ($i<$count) {

$split = split(":",$file[$i]);

        if($split[0] == $user) {
            $retval = false;
                break;
        }

++$i

 }
return $retval;
}

So, if this function returns a true value, the rest of the script should
proceed:

if (valid_name($user)) {

...rest of script here....

}

However whenever I run the script it always returns a 'true' value, even
when I try to use a username I know already exists in the .htpasswd file. I
discovered this by echoing the return value of the function and it always
shows '1'. What am I doing wrong here?

I look forward to your reply

Thanks,
Vamsi
